SAFETY INFORMATION
EAU10332
THIS MACHINE IS A SINGLE TRACK
VEHICLE. ITS SAFE USE AND OPERATION IS DEPENDENT UPON THE
USE OF PROPER RIDING TECHNIQUES AS WELL AS THE EXPERTISE OF THE OPERATOR. EVERY
OPERATOR SHOULD KNOW THE
FOLLOWING REQUIREMENTS BEFORE RIDING THIS MACHINE.
HE OR SHE SHOULD:
● OBTAIN THOROUGH INSTRUCTIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
MACHINE OPERATION.
THE WARNINGS
● OBSERVE
AND MAINTENANCE REQUIREMENTS IN THE OWNER’S MANUAL.
● OBTAIN QUALIFIED TRAINING
IN SAFE AND PROPER RIDING
TECHNIQUES.
● OBTAIN PROFESSIONAL TECHNICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL
AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.
Safe riding
● Always
make
pre-operation
checks. Careful checks may help
prevent an accident.
● This machine is designed for
off-road use only, therefore, it is illegal to operate it on public streets,
roads, or highways. Off-road use
on public lands may be illegal.
Please check local regulations before riding.
● This machine is designed to carry
the operator only. No passengers.
● Many accidents involve inexperienced operators.
Make sure that you are qualified
and that you only lend your machine to other qualified operators.
Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
● Many accidents have been caused
by error of the machine operator. A
typical error made by the operator
is veering wide on a turn due to
EXCESSIVE SPEED or undercornering (insufficient lean angle for
●
●
1-1
●
●
●
the speed). Never travel faster
than warranted by conditions.
Ride cautiously in unfamiliar areas. You may encounter hidden
obstacles that could cause an accident.
The posture of the operator is important for proper control. The operator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the machine.
Never ride under the influence of
alcohol or other drugs.
Protective apparel
The majority of fatalities from machine
accidents are the result of head injuries. The use of a safety helmet is the
single most critical factor in the prevention or reduction of head injuries.
● Always wear an approved helmet.
● Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision that could delay seeing a
hazard.
● The use of a jacket, heavy boots,
1
SAFETY INFORMATION

●
trousers, gloves, etc., is effective in
preventing or reducing abrasions
or lacerations.
Never wear loose-fitting clothes,
otherwise they could catch on the
control levers, footrests, or wheels
and cause injury or an accident.
Never touch the engine or exhaust
system during or after operation.
They become very hot and can
cause burns. Always wear protective clothing that covers your legs,
ankles, and feet.
Modifications
Modifications made to this machine not
approved by Yamaha, or the removal of
original equipment, may render the machine unsafe for use and may cause
severe personal injury. Modifications
may also make your machine illegal to
use.
Loading and accessories
Adding accessories or cargo to your
machine can adversely affect stability
and handling if the weight distribution of
the machine is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or accessories to your machine. Use extra care
when riding a machine that has added
cargo or accessories. Here are some
general guidelines to follow if loading
cargo or adding accessories to your
machine:
Loading
The total weight of the operator, accessories and cargo must not exceed the
maximum load limit of 90 kg (198 lb).
When loading within this weight limit,
keep the following in mind:
● Cargo and accessory weight
should be kept as low and close to
the machine as possible. Make
sure to distribute the weight as
evenly as possible on both sides of
the machine to minimize imbalance or instability.
● Shifting weights can create a sudden imbalance. Make sure that accessories and cargo are securely
attached to the machine before
riding. Check accessory mounts
and cargo restraints frequently.
1-2
●
Never attach any large or heavy
items to the handlebar, front fork,
or front fender. These items, including such cargo as sleeping
bags, duffel bags, or tents, can
create unstable handling or a slow
steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this machine. Since Yamaha cannot
test all other accessories that may be
available, you must personally be responsible for the proper selection, installation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any accessories.
Keep these guidelines in mind for
mounting accessories in addition to
those provided under “Loading”.
● Never install accessories or carry
cargo that would impair the performance of your machine. Carefully
inspect the accessory before using
it to make sure that it does not in
any way reduce ground clearance
SAFETY INFORMATION
or cornering clearance, limit suspension travel, steering travel or
control operation, or obscure lights
or reflectors.
Accessories fitted to the handlebar or the front fork area can
create instability due to improper
weight distribution or aerodynamic changes. If accessories
are added to the handlebar or
front fork area, they must be as
lightweight as possible and
should be kept to a minimum.
Bulky or large accessories may
seriously affect the stability of
the machine due to aerodynamic effects. Wind may attempt to
lift the machine, or the machine
may become unstable in cross
winds.
Certain accessories can displace the operator from his or
her normal riding position. This
improper position limits the freedom of movement of the operator and may limit control ability,
therefore, such accessories are
not recommended.
●
●
●
●
Use caution when adding electrical accessories. If electrical accessories exceed the capacity of the
machine’s electrical system, an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.
Gasoline and exhaust gas
● GASOLINE IS HIGHLY FLAMMABLE:
Always turn the engine off when
refueling.
Take care not to spill any gasoline on the engine or exhaust
pipe(s)/muffler(s) when refueling.
Never refuel while smoking or in
the vicinity of an open flame.
● Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poisonous and may cause loss of
consciousness and death within a
short time. Always operate your
machine in an area that has adequate ventilation.
● Always turn the engine off before

leaving the machine unattended
and remove the key from the main
switch. When parking the machine, note the following:
The engine and exhaust pipe(s)/
muffler(s) may be hot, therefore,
park the machine in a place
where pedestrians or children
are not likely to touch these hot
areas.
Do not park the machine on a
slope or soft ground, otherwise it
may fall over.
Do not park the machine near a
flammable source (e.g., a kerosene heater, or near an open
flame), otherwise it could catch
fire.
When transporting the machine in
another vehicle, make sure that it
is kept upright and that the fuel
cock(s) are turned to “ON” or
“RES” (for vacuum type)/“OFF”
(for manual type). If the machine
should lean over, gasoline may
leak out of the carburetor or fuel
tank.

CAUTION:
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
CAUTION:
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha engine has been designed to use regular unleaded gasoline with a pump octane number
[(R+M)/2] of 86 or higher, or a research
octane number of 91 or higher. If
knocking (or pinging) occurs, use a
gasoline of a different brand or premium unleaded fuel. Use of unleaded fuel
will extend spark plug life and reduce
3-4
maintenance costs.
Gasohol
There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol containing
ethanol can be used if the ethanol content does not exceed 10%. Gasohol
containing methanol is not recommended by Yamaha because it can
cause damage to the fuel system or vehicle performance problems.

PRE-OPERATION CHECKS
EAU15591
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspection, to check the following points before each ride.
NOTE:
Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very short
time; and the added safety it assures is more than worth the time involved.

WARNING
This model is designed for
off-road use only. In most instances, it is illegal to ride this
model (either day or night) on
any public street or highway.
Never start the engine or operate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of consciousness and death within a
short time. Always make sure
that there is adequate ventilation.
Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised completely, it could contact the
ground and distract the operator, resulting in a possible loss
of control.
EAU16451
Starting and warming up a
cold engine
In order for the starting circuit cut-off
system to enable starting, one of the
following conditions must be met.
● The transmission is in the neutral
position.
● The transmission is in gear with
the clutch lever pulled.
EWA11320
●
●
WARNING
Before starting the engine,
check the function of the starting circuit cut-off system according to the procedure
described on page 3-11.
Never ride with the sidestand
down.
1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
3. Shift the transmission into the neutral position.
4. Turn the starter (choke) on and
completely close the throttle. (See
page 3-6.)
5-1
5. Start the engine by pushing the
start switch.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to preserve the battery. Do not crank the engine more than 10 seconds on any one
attempt.
6. After starting the engine, move the
starter (choke) back halfway.
ECA11130
CAUTION:
For maximum engine life, always

There is never a more important period
in the life of your engine than the first 20
hours of riding. For this reason, you
should read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
20 hours of operation. The various
parts in the engine wear and polish
themselves to the correct operating
clearances. During this period, prolonged full-throttle operation or any
condition that might result in engine
overheating must be avoided. However, momentary full-throttle operation
under load (i.e., two to three seconds
maximum) does not harm the engine.
Each full-throttle acceleration should
be followed with a substantial rest period for the engine. To allow the engine
to cool down from the temporary buildup of heat, cruise at a lower engine
speed.
●
After every hour of operation, stop
the engine, and then let it cool for
five to ten minutes.
● Vary the engine speed from time to
time. Do not operate the engine at
one set throttle position.
10–20 hours
● Avoid prolonged operation above
3/4 throttle.
● Rev the engine freely through the
gears, but do not use full throttle at
any time.
After break-in
Avoid prolonged full-throttle operation.
Vary the engine speed occasionally.
ECA10270
CAUTION:
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

Troubleshooting
Although Yamaha machines receive a
thorough inspection before shipment
from the factory, trouble may occur during operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting chart
represents a quick and easy procedure
for checking these vital systems yourself. However, should your machine require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the machine properly.
Use only genuine Yamaha replacement parts. Imitation parts may look like
Yamaha parts, but they are often inferior, have a shorter service life and can
lead to expensive repair bills.

While the open design of a machine reveals the attractiveness of the technology, it also makes it more vulnerable.
Rust and corrosion can develop even if
high-quality components are used. A
rusty exhaust pipe may go unnoticed
on a car, however, it detracts from the
overall appearance of a machine. Frequent and proper care does not only
comply with the terms of the warranty,
but it will also keep your machine looking good, extend its life and optimize its
performance.
Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and covers
as well as all electrical couplers
and connectors, including the
spark plug cap, are tightly installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets, sprockets, the drive chain and wheel
axles. Always rinse the dirt and degreaser off with water.
●
Cleaning
ECA10770
CAUTION:
● Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the affected area any longer than instructed. Also, thoroughly rinse
the area off with water, immediately dry it, and then apply a corrosion protection spray.
● Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use only
a soft, clean cloth or sponge
with mild detergent and water to
clean plastic.
● Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
7-1
●
cleaning products, solvent or
thinner, fuel (gasoline), rust removers or inhibitors, brake fluid, antifreeze or electrolyte.
Do not use high-pressure washers or steam-jet cleaners since
they cause water seepage and
deterioration in the following areas: seals (of wheel and swingarm bearings, fork and brakes),
electric components (couplers,
connectors,
instruments,
switches and lights), breather
hoses and vents.
For machines equipped with a
windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning compounds for plastic may leave
scratches on the windshield.
Test the product on a small hidden part of the windshield to
make sure that it does not leave
any marks. If the windshield is
scratched, use a quality plastic
polishing
compound
after
washing.
MACHINE CARE AND STORAGE
After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.
After riding in the rain, near the sea or
on salt-sprayed roads
Since sea salt or salt sprayed on roads
during winter are extremely corrosive in
combination with water, carry out the
following steps after each ride in the
rain, near the sea or on salt-sprayed
roads.
NOTE:
Salt sprayed on roads in the winter may
remain well into spring.
1. Clean the machine with cold water
and a mild detergent, after the engine has cooled down.
ECA10790
CAUTION:
Do not use warm water since it increases the corrosive action of the
salt.
2. Apply a corrosion protection spray
on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
After cleaning
1. Dry the machine with a chamois or
an absorbing cloth.
2. Immediately dry the drive chain
and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine
chrome, aluminum and stainless-steel parts, including the exhaust system. (Even the thermally
induced discoloring of stainless-steel exhaust systems can be
removed through polishing.)
4. To prevent corrosion, it is recommended to apply a corrosion protection spray on all metal,
including chrome- and nickel-plated, surfaces.
5. Use spray oil as a universal cleaner to remove any remaining dirt.
6. Touch up minor paint damage
caused by stones, etc.
7-2
7. Wax all painted surfaces.
8. Let the machine dry completely
before storing or covering it.
EWA10930

WARNING
Make sure that there is no oil or
wax on the brakes or tires. If
necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or acetone, and wash the tires with
warm water and a mild detergent.
Before operating the machine
test its braking performance
and cornering behavior.
ECA10800
CAUTION:
● Apply spray oil and wax sparingly and make sure to wipe off
any excess.
● Never apply oil or wax to any
rubber and plastic parts, but

Storage
Short-term
Always store your machine in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA10810
CAUTION:
● Storing the machine in a poorly
ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to

● To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemicals are stored.
Long-term
Before storing your machine for several
months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. For machines equipped with a fuel
cock that has an “OFF” position:
Turn the fuel cock lever to “OFF”.
7-3
3. Drain the carburetor float chamber
by loosening the drain bolt; this will
prevent fuel deposits from building
up. Pour the drained fuel into the
fuel tank.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. Perform the following steps to protect the cylinder, piston rings, etc.
from corrosion.
a. Remove the spark plug cap
and spark plug.
b. Pour a teaspoonful of engine oil
into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit sparking during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder wall with oil.)
e. Remove the spark plug cap
from the spark plug, and then
install the spark plug and the

YAMAHA EXTENDED SERVICE (Y.E.S.)
Keep your Yamaha protected even after your warranty
expires with genuine Yamaha Extended Service (Y.E.S.).
In addition, Travel and Recreation Interruption Protection
(TRIP) is included at no extra cost. TRIP gives you up to
$150 reimbursement per occurrence for any reasonable
expenses you incur because your Yamaha needs
covered service: replacement vehicle rental, emergency
towing, phone calls, even food and lodging when you are
away from home. This superb coverage goes into effect
when you purchase Y.E.S., so it applies to any warranty
repairs as well as covered repairs during your entire
Y.E.S. plan period.
Y.E.S. is designed and administered by Yamaha Motor
Corporation to provide maximum owner satisfaction. You
get uninterrupted factory-backed coverage for extra
peace of mind.
Y.E.S. is flexible. You choose the plan that’s right for
you: 12 months, 24 months, 36 months or, on certain
models, even 48 months beyond your warranty period.
Y.E.S. is designed and administered by the same
Yamaha people who handle your warranty – and it
shows in the comprehensive coverage benefits. There
are no mileage limitations. Coverage isn’t limited to
“moving parts” or the “drive train” like many other plans.
And Y.E.S. covers manufacturing defects just like the
warranty. See the sample contract at your Yamaha
dealer to see how comforting uninterrupted factorybacked protection can be.
3
Y.E.S. coverage is honored at any authorized Yamaha
dealer nationwide.
4
Y.E.S. coverage is transferable to a new owner if you
sell or trade-in. That can make your Yamaha much more
valuable!
5
This excellent Y.E.S. plan coverage is only available to
Yamaha owners like you, and only while your Yamaha is still
within the Yamaha Limited Warranty period. So visit your
authorized Yamaha dealer to get all the facts. He can show
you how easy it is to protect your investment with Yamaha
Extended Service.
You don’t have to pay anything for covered repairs.
There’s no deductible to pay, and repairs aren’t
“pro-rated.” You don’t have any “out-of-pocket” expenses
for covered repairs.
